Patent DE-3727794-A1 (DE)
Title: Method of determining the liquid absorption of pulverulent solids
Inventor: MARKERT JUERGEN DR
IPC: G01N11/14
Filed: 1987-08-20
Abstract: The liquid absorption of pulverulent solids is, for example, measured as "DBP number" in the case of carbon black (by the Cabot method) or as "oil number" in the case of pigments and fillers. The known methods give results which are only moderately reproducible when the bulk density of the powder is extremely low. The new process can be used in a wide range of bulk density of the powder. The powder particles are only slightly stressed mechanically. Agglomeration of the particles is avoided. The powder is stirred in a planetary mixer and fluidised. The liquid to be absorbed is optionally preheated and conveyed continuously (without pulses) to the application device and is there atomised. From the measured course over time of the torque at the stirrer motor, various parameters are taken from which the liquid absorption is calculated. The new process can be used on powders having a bulk density of from 0.05 to 3 g/cm<3>. The absorption of ethylene glycol or dibutyl phthalate by active silica, carbon black or light-coloured fillers was measured.

Patent DE-3738253-A1 (DE)
Title: Method and appliance for filtration of a liquid
Inventor: BAUR ROLF DIPL ING
IPC: B01D29/66
Filed: 1987-11-11
Abstract: A method for the filtration of a liquid, especially beer, wine, etc., to give a filtrate and a filtration residue. The liquid is directed, as a slurry (unfiltered liquid), under pressure, into a slurry chamber via a filter medium into a filtrate plenum, and thence is discharged. The separation is carried out exclusively as a cake filtration (surface filtration). At intervals, the filtration is interrupted for removing the filtration residue from the filter medium. An essential aspect in the process is that the slurry is filtered via the filter medium without the use of filter aids. The filter medium is formed by a rigid, porous body which is at a small distance from the inner wall of the pressure vessel.
Patent DE-3738291-A1 (DE)
Title: Method for constructing a bridge supporting structure of prestressed concrete
IPC: E01D21/06
Filed: 1987-11-11
Abstract: In the sectional construction of the superstructure of a multi-span, continuous-girder bridge supporting structure of prestressed concrete by timed shifting, the prestressing elements are arranged within the overall height of the superstructure but outside the concrete cross-section, unconnected, and are guided and anchored in pilaster strips close to the concrete cross-section. Once the superstructure has attained its final position, some of the prestressing elements which are required during construction for the approximate central prestressing of the concrete cross-section and run in a straight line are relaxed and after loosening the anchorages are re-installed and tensioned again in a position corresponding to the static requirements of the final state. This can take place either such that prestressing elements are transferred into another position in the superstructure cross-section, for example, at the support, from the bottom boom to the top boom or, in the bay, from the top boom to the bottom boom, or while retaining their position in the longitudinal direction are pushed into new positions, thus for example, in the bottom boom, from the support region to the bay or, in the top boom, from the bay region to the support. Consequently, not only is optimal adaptation to the particular loading conditions possible, but also a significantly better utilisation of the prestressing steel, with the result that the requirement of prestressing steel in the production of a bridge by timed shifting is no greater than in the case of a corresponding bridge produced on falsework.

Patent DE-3818952-A1 (DE)
Title: Collecting arrangement in track installations, for protecting ground and groundwater from the entry of harmful substances
Inventor: BRAUN WILHELM DIPL ING
IPC: E01B1/00
Filed: 1988-06-03
Abstract: Track installations have hitherto been secured by means of track-supporting slabs formed as concrete tubs, which require a special substructure and can only be laid using heavy equipment, or steel covers which inadequately cover the immediate rail area. The new collecting arrangement is to enable a continuous sealing of the track area to be secured, is to be capable of being installed and removed rapidly and without great effort, is to enable inexpensive series production as a result of invariable components and is to contribute to the standardisation of the systems through its versatility. The rails with their ribbed slabs are enclosed by collecting troughs (3) raised up to the height of the rail head and closed at the ends, on the rising side walls of which there are laid collecting tubs (21) or covering slabs (18) which, together with the collecting troughs, drain into open channels (17, 23). The collecting arrangement is particularly suitable for tank wagon refilling installations, filling stations for rail vehicles, passenger train washing installations and locomotive sidings, and in the case of protection against dripping quantities the drainage can be simplified in that it takes place merely via the collecting troughs (3), which are in this case open. <IMAGE>
Patent DE-3823884-A1 (DE)
Title: Linear potentiometer (electrical position sensor)
Inventor: HANDEL HUBERT DIPL ING
IPC: H01C10/38
Filed: 1988-07-14
Abstract: Such a potentiometer is unsuitable for use in a liquid or in a moist area, since moisture passes into the housing via the inadequate seal on the operating rod. In order to keep moisture away, the operating rod is provided with a sealing tube which also carries out the displacement movement of the operating rod. The sealing tube passes through a building wall and is supported there via two seals which are arranged in series (in a row). A chamber which is filled with grease or oil is arranged between the seals and forms a liquid-repellent oil or grease film on the surface of the sealing tube. This effect is also assisted by filling with electrically non-conductive oil, which is introduced in the housing cavity which accommodates the resistance element.

Title: Liquid dispenser (apportioner) with self-controlling liquid level in the consumer bowl by means of air quantity exchange between two air chambers
Inventor: AUMUELLER FRITZ
IPC: B67D7/00
Filed: 1988-10-11
Abstract: Advantages with respect to previous liquid dispensing (apportioning) methods: The supply container (1) can be refilled without interrupting the dispensing process and in a simpler way, no opening seals or valves being able to cause susceptibility to interference. The height of the liquid level (12) in the consumer bowl (6) of the container (2) is easily regulated, in that a hook-shaped tube (15) is immersed and air is led to or from the spaces (8) and (9). The air pressure of the human lungs is sufficient. The consumer container (2) can be moved vertically and horizontally without altering its level (12) and independently of the supply container (1). The height difference between the two containers can be selected practically arbitrarily, since the limitation on the use of vacuum ceases to exist. <IMAGE>
